WELLINGTON PARKER .KDIDEB, OF BOSTON, MASSACHUSETTS, ASSIGNOB TO THE NOISELIESS TYPEWBITEB COMPANY, OF KIDDLETOWN, CONNECTICUT, A CORPO- BATION OF CONNECTICUT.

TYPE-WRITING mm To all whom it may concern:

Be it known that I, Wmmomx Plunges Kmonn, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented eer tain new and useful Improvements to Type- Writing Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to so which it appertains to make and use the same.

This invention relates to typewritmg ma chines, and with to the more specific features thereof, to ribbon mechanism there- !5 for. One of the objects of this invention is to l provide a simple and practical ribbon mech anism for typewriting machines. Another object is to provide improved in devices of the class stated which w1ll be simple to construct and cheap to manufactare.

A further object is to provide ribbon mechanism particularly adapted for visible typewriting machines, and which will be eficient an dependable in operation.

Other will be in part obvious and in out The invtmtion consists in the featurm of construction, combinations of elements and of aris which ill be exeanpl ified in the construction hereinaftermtfortmandthesco oftheapplication of which will be in 'cated in the following claims.

In the accompanying drawings, wherein is shown one of many possible embodiments of myinventioml igurelisalongitudinal view of a typewritmg machine showing such partsasaresuficienttoillustratethepresent invention; Fig. 2 is aperspedive view .ofcertainpartsshowninFig. 1; andFigs.

lar parts throughout the several views of the drawings.

Referring to these drawings in detail, 1 represents the base or framework of the machine, provided at each side of the rear portion wlth upwardly curved members 2- and 3 having a member 4: extending there hetween forming a rigid abutment or backmg for a platen carriage which is adj ustable fore and aft of the machine in any desired manner. This platen carriage comprises opposlte end plates, one of which is denoted by the numeral 5 in Fig. 1, and carries therebetween a paper feed roller 6 and a fiat platen 7, adapted to receive the printing impresslon, extending upwardly from which lsanerasingtable8. Pa isfedbetween therearofthe tabe8andthepaper table 9 under the f roller 6 and over the flat platen 7. The other parts of the carnage, such as the complementary paper feed rollers, Indicating means and the like, are herein omitted for the sake of clearnes. This carriage reciprocates from right to left in a vvell Iii Elv n manner unler the action of :1 mg drum an an escapement men si mi sm, which are also omitted and is shrfizable up and down from a normal intermediate position by the key actuated means, such as herein shown and described, This shift mechanism comprises, in brief, a roller 10, engaging a channel bar 11 on the arnage, and carried by a stud 12 mounted upon a lever 13, the upper part of which is held against transverse movement by means of a connecting member 14 supported by the frame of the machine. The lower part of the lever 13 is provided with a roller 15 engagingacamslotlfiinablockl'i'securcdto thebm Thiscamslotmissubdzantiallyin the form of a reverse curve extending up solidly 2from right to left, as clearly shown 1n 1g.

Intermediate the ends of the lever 13 is a pm 18 forming a pivot point for a link 19 connected with an upwardly extending arm 20 mounted on a rock shaft 21. The forward end of this rock shaft 21, or that part near the keyboard, is provided with a horizohntally d 1mlmenzdibear 22, the ends of w 'ch are 1! ap to engaged, msmfl tively, by downwardly curved hook memhers 23 and 24, supported from a rock 1aft 25, The hook member 23 is preferably an whanb a wed. in: similar mnar'udiflci'ent MM, 7 In.
